From 783e9b4826b95e53e33c42db6b4bd7d89bdff147 Mon Sep 17 00:00:00 2001 From: Wen Congyang Date: Mon, 7 May 2012 12:10:47 +0800 Subject: introduce a new monitor command 'dump-guest-memory' to dump guest's memory The command's usage: dump-guest-memory [-p] protocol [begin] [length] The supported protocol can be file or fd: 1. file: the protocol starts with "file:", and the following string is the file's path. 2. fd: the protocol starts with "fd:", and the following string is the fd's name. Note: 1. If you want to use gdb to process the core, please specify -p option. The reason why the -p option is not default is: a. guest machine in a catastrophic state can have corrupted memory, which we cannot trust. b. The guest machine can be in read-mode even if paging is enabled. For example: the guest machine uses ACPI to sleep, and ACPI sleep state goes in real-mode. 2. If you don't want to dump all guest's memory, please specify the start physical address and the length.
